We conduct a study in which subjects trade stocks in an experimental market while we measure their brain activity using functional magnetic resonance imaging. All of the subjects trade in a suboptimal way. We use the neural data to test a “realization utility” explanation for their behavior....

A number of authors have suggested that investors derive utility from realizing gains and losses on assets that they own. We present a model of this quot;realization utility,quot; analyze its predictions, and show that it can shed light on a number of puzzling facts. These include the...

We use measures of neural activity provided by functional magnetic resonance imaging (fMRI) to test the "realization utility" theory of investor behavior, which posits that people derive utility directly from the act of realizing gains and losses. Subjects traded stocks in an experimental market...
